JModelica中的Python/Pyomo错误

Question

我已经为JModelica (基于python)安装了一个商业解算器包(OCT) -->当我想通过"Ipython“打开JModelica时，我得到了以下错误信息：

Traceback (most recent call last):

  File "C:\OCT-1.0b1\Python27\scripts\ipython-script.py", line 5, in <module>

    from pkg_resources import load_entry_point

  File "C:\OCT-1.0b1\Python27\lib\site-packages\pkg_resources.py", line 2825, in

 <module>

    add_activation_listener(lambda dist: dist.activate())

  File "C:\OCT-1.0b1\Python27\lib\site-packages\pkg_resources.py", line 710, in

subscribe

    callback(dist)

    add_activation_listener(lambda dist: dist.activate())

  File "C:\OCT-1.0b1\Python27\lib\site-packages\pkg_resources.py", line 2260, in

 activate

    map(declare_namespace, self._get_metadata('namespace_packages.txt'))

  File "C:\OCT-1.0b1\Python27\lib\site-packages\pkg_resources.py", line 1836, in

 declare_namespace

    path = sys.modules[parent].__path__

KeyError: 'pyomo'

我通过spyder/Anaconda2 (64位)使用pyomo

如果有人能帮我，那就太好了！

可以在virtualenv中安装pyomo，避免与JModelica冲突：
